This market tracks the performance of a major stock market index on a specific future date and time, allowing participants to speculate on whether the index will surpass certain threshold values.
The market resolves based on whether the Nasdaq 100 index value at 4pm EDT on October 19, 2026 exceeds specified thresholds, with each market having a unique threshold value. All markets close on October 19, 2026, and expire either when the index value is first reported or one week after the close date, whichever comes first. The rules reference modifications to the source agency and underlying for index markets as per the Kalshi Rulebook.
